Large blue Samsonite suitcase, 28 inches, left on boardwalk

I lost my large blue Samsonite 28-inch hard-shell suitcase yesterday around 3pm. It was left near the South Coast Boardwalk behind the Lobster Shack on Seabreeze Avenue, just as the sun was starting to dip. The case has scuffs on the corners, a stiff zipper, and the bright red interior lining is visible if you peek inside. On the top corner there’s a white whale sticker and a lime-green luggage tag with my initials 'P.P.' dangling from the handle. Inside I kept a small photo of my grandmother—it's sentimental to me, and I’d be incredibly grateful to get it back.
